"Brendan our tech service guy was professional, efficient and serviced our yearly checkup on our filter tank. He called before getting to our home and was right on time. I always ask a million questions and he was very knowledgeable! I would definitely recommend Blue Atlantic!"

"We lost water pressure and had no water. Tom called me back immediately and arrived late evening to check out our problem. He had the tank and other equipment on his truck to complete the repair the same evening. Very pleased with the service. Would highly recommend this company."

"We lost our water and Rick and his team came out late evening to determine the problem. They returned the following day and installed a new well pump. Georgina kept in touch as far as arrival times both days. In addition, they installed and service our water treatment system. Excellent customer service and highly recommend!"

"This was not an emergency repair, we were fortunate to be able to schedule the replacement about a week in advance. Heil sent an estimator to look at the space and make a recommendation. We originally wanted a Hybrid system but they advised against it given the space and need to collect/vent moisture. We selected a 75 gallon electric water heater. On the scheduled day, They were on time, removed the old water hearter and installed the new one - professional and courteous the whole time. Unfortunately, the new heater leaked the same day. They returned and made a temporary patch until they could return the next day with a replacement part. They returned, replaced the part and after they left we found that the tank leaked again in another place. They returned the next day and before we could insist that we wanted a different tank (clearly an out of the box failure on this one) they said they would replace the tank which they did. Our first, second and third experiences with Heil were all great with customer service and technical expertise. The inconvenience of multiple extra days without hot water and having to be there for four visits was unexpected and unfortunate however Heil responded correctly and made it right. You can get the measure of a company not only when things go right but also how they respond when things go wrong. We would use them again."
